Heat Staking Vs. Ultrasonic Threaded Inserts

Threaded inserts installed with heat or ultrasonics provide plastics processors with high performance at a low cost. Discover when to use them and how. (Sponsored Content)

With the heat staking method, heat is applied to the threaded insert, melting the plastic around it as it is inserted into the part. See it in action HERE.

Both heat staking and ultrasonic processes for installing threaded inserts can be used by plastics processors looking for strong joints and reusable threads.

Heat staking and ultrasonic insertion starts with a pre-formed hole that can be created in the molding process or drilled afterwards. With heat staking, heat is applied to the threaded insert, softening the plastic as it is pushed into the part. Alternatively, ultrasonic welding uses a vibration frequency to soften the plastic for thread insertion.

Both types offer high overall performance for thermoplastics applications, but require a few careful considerations…READ MORE.
